Let me set a hypothetical scene for you. Imagine a new trendy fitness class that everyone is joining to take at the local gym. You’ve heard of Hot Yoga, but this is a new kind of class called Dark Yoga. You set up your mat in the class for the first time, and the lights go out. You hear the soft voice of the instructor come through the microphone. “Welcome into dark yoga class. alright everyone, lets begin by taking a deep breath in, hold, and breathe out as you slide down into pigeon position. Wonderful, feel that stretch as you lean to the side like this, and slowly pull up into Camel…” Um, What? Doesn’t sound like a class that will have a lot of participants right? I mean, how in the world are you going to follow the class with this kind of setting? What in the world is a pigeon position? Of course this would not be a functional class, and yet there is a demographic of people in our world that deal with this every single time they want to learn or do fitness. In fact, over 3.4 million people in the United States alone, might find themselves trying to function in “dark yoga”classes…I’m talking of course about people who are visually impaired.
